A corner structure comprises: a fixed member fixed to a corner of a storage tank; a movable member supported on the fixed member so as to be linearly movable; a stop member attached to the fixed member to prevent the movable member from being detached from the fixed member; and a heat insulating member disposed between a sealing wall and a hull. The fixed member comprises a guide portion provided with a guide recessed portion, the movable member comprises a guide protruding portion inserted into the guide recessed portion, and the width and the length of the guide protruding portion are smaller than the width and the length of the guide recessed portion, so that the movable member can be supported on the fixed member to be movable in the longitudinal direction and in the direction perpendicular to the longitudinal direction.

Disclosed is a pump tower disposed inside a liquefied gas storage tank so as to supply or discharge liquefied gas to/from the inside of the liquefied gas storage tank. The pump tower includes a discharge pipe for discharging the liquefied gas in the liquefied gas storage tank, an emergency pipe equipped with an emergency pump at the lower end thereof, and a charge pipe for supplying the liquefied gas into the liquefied gas storage tank. The pump tower further includes a support provided on the bottom of the liquefied gas storage tank for enabling the vertical displacement of the pump tower and restricting the horizontal movement and rotation thereof. The support includes a lower body fixed to a hull side, an upper body fixed to a pump tower side and a wedge member interposed between the lower body and the upper body.

The present invention relates to an anchor structure able to actively cope with hull deformation, and to a liquid natural gas storage tank and a production method for a liquid natural gas storage tank comprising the anchor structure. According to one embodiment of the present invention, an anchor structure is provided wherein an anchor structure, for linking a sealing wall and an inner wall of a liquid natural gas storage tank, comprises: an anchor member adapted such that a joining part, which is joined to the sealing wall, can slide horizontally; and a thermally insulating material formed around the anchor member.
A corner structure according to an embodiment of the present invention comprises: a fixed member (110) fixed to the inner surface of a corner of a storage tank; a movable member (130) supported on the fixed member so as to be linearly movable; a stop member (140) attached to the fixed member to prevent the movable member from being detached from the fixed member; and a heat insulating member (150) disposed between a sealing wall and a hull. The fixed member comprises a guide portion (114) provided with a guide recessed portion (114a), the movable member comprises a guide protruding portion inserted into the guide recessed portion, and the width and the length of the guide protruding portion are smaller than the width and the length of the guide recessed portion, so that the movable member can be supported on the fixed member to be movable in the longitudinal direction and in the direction perpendicular to the longitudinal direction.
